//! Crate ruma-api-macros provides a procedural macro for easily generating

//! [ruma-api](https://github.com/ruma/ruma-api)-compatible endpoints.

//!
|
|
//! This crate should never be used directly; instead, use it through the
|
|
//! re-exports in ruma-api. Also note that for technical reasons, the
|
|
//! `ruma_api!` macro is only documented in ruma-api, not here.
